But that doesn't interface with ones own program? I'm not talking 
about a standalone repl but something what can use from their own 
program and then use that command line interface of it(or just 
send command through text) and interact with the original program:

string foo() { writeln("foo"); }
void main()
{
     repl.init();
     writeln(repl.exec("foo()"));
     writeln(repl.exec(readline()));
     repl.OpenInterface(); // <- A new command window is open that 
lets us run code from it, code that has access to this programs 
code.
}


Or whatever.
